The glassware in this this image should not be blue-gray-green, but when I lower the fog color or intensity, it disappears. I’ve always spent WAY too much time tweaking glass. Any great ideas welcome. Mediocre ideas also welcome.
I would try these options in sequence:
Option 1, desaturate fog color and play with fog multiplier and fog bias (maybe set it +1 to decrease the edge darkening effect.)
Option 2, add reflect on backside to improve reflections realism
Add something in the environment to make sure there is something to reflect.
Option 3, increase max depth for refl/refr (10 should work)
